Comment 2 for bug 1746783

Looks like you may have a configuration error:

ImportError: Class LVMISCSIDriver cannot be found

Also, your statement of "pvcreate command for preparing storage device on my storage node ... is not working" is a concern. If you can't even create the LVM for Cinder to use, neither Cinder nor Nova are even interesting to look at at that point.

The /dev/vd* devices are what show up in virtual machine instances. On the compute host they will be the normal /dev/sd* devices.
